LUBRICATING SYSTEM FOR WIRE-DRA'WING MACHINES.

Application led. July 1, 1921.

To all w imm may concern Be it known that 1', lVILLIAM D. PinRsoN, a citizen of the United States, residing at Vsfaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Lubricating Systems for VVire-Drawing Machines, of which the following is a specilication, reference being' had therein to the accompanying drawings.

This invention relates to a new and useful oiling syst-em for wire drawing` machines and has for its object, among other things, to provide a system whereby all of the bear ings and several gears may be kept constantly provided with a lubricant, which may be used over and over again and obtained either from a supply exterior to the machine or from a suitable reservoir connected with the machine and into which the lubricant drains after beingused.

To these and other ends, `my invention consists in the new and improved oiling system for wire drawing machines having` certain details of construction and combinations of parts as will be hereinafter described and more particularly pointed out in the claims.

Referring` to the drawings in which like numerals of reference designate like parts inthe several figures,-

l*1 igure 1 is a sectional plan view of an improved wire drawing` machine of the conventional type havingmy improved oiling system connected therewith;

`Figure L), is a front elevation thereof; and

Figure I is a similar cross-sectional view.

In a wire drawing` machine where there are many wire drawing` drums and a block, each of which is mounted on a shaft and operated with beveled gears, it has heretofore been a difficult task to keep all of the journals and gears sufliciently lubricated, with the consequent disastrous result that the work is improperly done and the parts subjected to undue wear. To, therefore, overcome this difficulty, I provide means for oiling the gears and to feed oil to all of the bearings. This is accomplished by a system whereby the lubricant or oil may be originally drawn from a source of supply outside of the machine by the same pump that operates the oiling system of the machine and when sufficient oil has been thus Serial No. 481,832.

obtained shut off this source of supply. Thereafter the oil after it has passed over the bearings and beveled gears is used until by evaporization or other means this supply has been exhausted. In connection therewith l have designed means whereby the system for oiling the journals is separate and distinct from that for oiling` the beveled gears and one can be in operation while the other is not or bot-h can be operated at the same time as may be desired.

In the drawings which show a single unit of a wire drawing machine of the conventional type, 10 is the base plate which is modified, however, from the usual form by forming` a reservoir 13 therein by the walls 11 and 12, the latter being` upon an incline so that the oil will flow toward that portion of the reservoir 13 having the strainer 14 therein.

Supported above the base plate by the standards 15 is a table 16. The main driving shaft 17 is journaled in suitable bearings 18 and fixed thereon are the bevel pinions 19 that mesh into and drive the bevel gears 2O upon the lower end of the vertical shaft 21 that is journaled in the bearings 22 and 28 and has a drum 211 fixed to the upper end thereof.

All of the mechanism below the table 16 is inclosed, suitable cover plates 25 and 26 being,l provided for this purpose,'these beingn so designed as to be readily attached or ldetached and having' such covered openings therethrough may seem desirable.

All of the mechanism above described, eX- cept the provision of a reservoir in the baseplate and the inclosing of the mechanism by the cover plates and 26, is old and well known in the art.

A rotary oil pump 27 of any preferred construction driven from the shaft 17 by a belt 28 connecting the pulley 29 on said shaft with a pulley 30 connected with the pump, draws in and forces the oil through my improved system. A four-way valve 31 having a handle 83 is connected with the pump through suitable pipe connections 32 and with the strainer 14E through the pipe conpipe I7 connected with the pipe the valves 39 and ett). Connected with the valve 39 is the gear feed pipe #il and with the valve 40 the bearing feed pipe a2. As the principal Supply ot oil passes through the main supply pipe 38, manipulation of the valve 39 either opens or closes the pipe al for admission of oil to the gears, and likewise by manipulation of the valve d0 the supply ot' oil to the bearing teed line. Thus one line may be supplied with oil while the other is entirely shut ott and the volume ot' oil to both may be equally controlled.

Connected with the gear feed pipe l1 is a jet pipe 43 having valve lf-l therein which projects 'from the pipe, eil and terminates adjacent to the meeting tace of the pinion 19 and gear E20 so that when the valve Illis open, the oil under pressure is squirted into the teeth of both the pinion and gear.

The bearings 1S are supplied with oil from the pipe Ll5 leading Yl'roin pipe 4t2 and having' a suitable valve l-(S therein. rlhe bearing .23 oit the vertical shai't 2li. is supplied with oil under pressure through the 42 and having a suitable valve 4S therein, and the bearing 22 is similarly supplied with oil through the pipe 49 having a valve 5() therein.

The original source of oil supply is obtained through the pipe 36 at which time the handle 33 ot the valve 3l and the handle 51 ot' the valveBI are in the positions shown by full lines in Figure 1 and the valves 39 and t() are both closed. After a sutlicient supply has been thus obtained, the handles 33 and 5l are moved to the broken line positions in Figure l and the valves 39 and fl() lare opened and a continuous supply ot oil .is then brought to the pipes Lll and 42 from which the'gears and bearings are suitably supplied `by the piping as above described.

The oil after passing over the gears and bearings, drops therefrom intothe reservoir 13 and passes through the strainer pump and the piping system as above described.

To remove all ott the oil from the machine, either to clean or repair the niechanisn'i; the handle 5l o't` the valve 34 is moved to the broken line position in Figure l and the handle 33 o't the valve 31 remains in its 'full lineposition, at which time the oil is withdrawn from the reservoir and Jforced through the valve 34C and pipe 3G to the original source'of supply.

Minor changes and alterations may be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limitmyself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope oi the appended claims.

lhat I claim as new and desire to secure by Letters Patent, is:

l. In a wire drawing machine, a base plate having'a reservoir therein; a table supported above said base plate; cover plates between said base plate and table; a pump; a connection between said `reservoir and pump; a connection between said pump and each of the journals ot the machine; another connection between said pump and each pair of gears of said machine, the said journal connections being separate and independent from the gear connection.

2. In a wire drawing machine, a base, plate having a reservoir therein; a table supported above said base plate; cover plates between said base plate and table; a pump; a connection between said reservoir and pump; a connection between said pump and each of the journals ot the machine; another connection between said pump and each pair of gears ot said machine, the said journalconnection heilig separate and independent from the gear connections; and a valve between said pump and connections whereby oil may be delivered to each-of said connections through said pump from an exterior source ot supply or from said reservoir.

3. In a wire drawing machine, a base plate having a reservoir therein; a table supported above said base plate; cover plates between said base plate and table; a pump; a connection between said reservoir and pump; a connection between said pump and each of the journals of the machine; another connection bet-ween said pump and each pair ot' gears ot said machine, the said journal connection being separate and independent iirom the gear connections; a valve between said pump and connections whereby oil may be delivered to each ot said connections through said pump from an exterior source o't-supply or from said reservoir; and valve connections whereby the oil 'from said pump to the journal and gear connections may be entirely shut ott and the oil from said reservoir withdrawn therefrom and delivered through said pump outside ot the machine.

In testimony whereof, I have hereunto atlixed'my signature.
